请解决一下问题(用java编写)

import java.io.*;

public class Test {
public static void main(String[] args) throws Exception{
BufferedReader br1 = new BufferedReader(new FileReader("D:\\aaa.txt"));
BufferedReader br2 = new BufferedReader(new FileReader("D:\\bbb.txt"));
FileWriter pw=new FileWriter("D:\\ccc.txt",true);
BufferedWriter bw = new BufferedWriter(pw);
String lineContent = null ;
while( (lineContent = br1.readLine()) != null){
bw.write(lineContent);
bw.newLine();
}
while( (lineContent = br2.readLine()) != null){
bw.write(lineContent);
bw.newLine();
}
bw.close();
br1.close();
br2.close();
pw.close();
}

}
